Idiopathic Hypertrophic Pachymeningitis Presenting with Uveitic Glaucoma.

A 73-year-old man presented with uveitic glaucoma associated with headache. Because there were no active inflammatory signs, synechiolysis and cataract extraction were performed. Even after lowering intraocular pressure, he repeatedly complained of headache, but no neuroimaging was performed. Acute bilateral visual loss was occurred 3 months after cataract surgery. Ophthalmologic examination revealed bilateral optic neuritis and a Gd-DPTA-enhanced cranial magnetic resonance imaging (MRI) showed thickened enhancement of the dura and optic nerve sheath. A final clinical diagnosis of idiopathic hypertrophic pachymeningitis associated with optic neuritis was made.
